I always recommend a good, fast dual core; around 3ghz, with a motherboard that will accept a quad core upgrade some time in the future. You would save so much just going for a fast dual core and at least 4gigs DDR2 with the option to upgrade to 8gigs in a year or so. DDR3 and quads just dont really seem worth the price difference to me just yet. But by all means, Intel's quads are very decent at the moment, and if you have the money to burn... You also didn't mention your monitor/resolution you'll be running?
I am trying to set it up so I will not need to touch it for 2+ years. It just seems like this rig could handle anything that will be coming out for a couple years. I will give your input some consideration before I make my purchase. Thanks.
inkace, I am generally not a proponent of waiting, but there are two reasons to wait a little while now. First, there are 45 nm GPU cores coming from nVidia real soon now. Second, Phenom II is also coming from AMD. Both may have an effect on the pricing of everything else - and might not .
Present configuration: you can save some money on the hard drives. Current "performance" drives (WD Black's for example) are almost as fast as the Raptors and, because of the higher data density, have higher sustained throughput and they run cooler. And I wouldn't build a RAID array without an external controller card.
Will your (AMD) CPU cooler fit the i7 CPU?
And minor, really minor: I prefer the Samsung SATA DVD r/w drives.
